What mother boards did you go with? 400 bucks for 10 is pretty awesome. I'm only building 4 to begin with, i don't need it more then that for now. But am looking for a good deal. I'm thinking of going with theAMD Phenom II X4 965 Quad-Cor

Or are there any Render farm softwares that people suggest for windows, not linux?

Qube and Deadline seem to be the popular choices. We're using Qube right now and have been reasonably happy -- though in terms of price, I admit that DrQueue is looking awfully tempting (it's free, which would probably make it my personal preference if I was building my own farm. As I am broke).

While we're liking Qube, do not be swayed by the beautiful pictures on the website. The program does not look like that. The Qube and Deadline front-ends and submission dialogs are pretty much identical.

Ya, your net render computer.... while i'm going to use my workstation, sometimes i will need to render at home or need to use my computer for other things. So i was thinking of getting a separate render server to send files to. Although, I think i'm going to hold off for a bit.

If you have the rack and only two blades, you should have plenty of room to expand as time goes on.

So far I have 5 regular macPro´s running on a NET render. So I´ll add "pizzaboxes" 2 at a time. Hopefully it will add sufficient power, but once you go down that road you can never get enough power. My friend have 422 cpu´s in his farm and he is still short.... I have a long way to go i guess.

Aroma - when you get this done could you post the specs of the machine you build your scenes in including OS, specs, then also that of the render farm and pictures? I researched this about a year ago and am currently about to be in the process of computer shopping and I would like to build myself a little render farm just like this. Currently I run a mac pro which obviously would have issues matching with a project like this.

Parts are starting to flow in. I bought the case and put it together, and found a bundle of 5 120w power supplies on ebay for $45. Also found a batch of 5 80gb laptop hard drives for $145 on ebay. The helmer case was more expensive than anticipated (listed at $35) because of the shipping fees (wasn't available in the store). The case ended up running $65. NOW the AMD 8 core 3.6Ghz chips are out. I think I will go with those, but it looks like they are around $270 a piece and I will have to buy them from multiple retailers since nobody is selling more than one or two per person. I am still waiting on a good deal for 5 am3+ mini/micro atx motherboards.

What I am looking for now, is the distributed rendering solution. I was looking at the free Dr Queue, but it sounds like its dying and only supports Mental Ray in regard to C4D. Today I re-discovered Smedge, which I used years ago briefly and not really first-hand. Looks like Smedge supports C4D but not mental ray for C4D nor Vray for C4d, although it mentions Vray and Mental ray for Maya.

Does anyone have recommendations for a distributed network rendering software?

Everything is ordered. Parts are in the mail . Everything totaled out to be $3,260 but I still need a monitor. It will have 5 machines, each with an 8 core 4.2ghz (overclocked) processor and 16gb of ram. The core cost was more like $2000 for the motherboards, processors, hard drives and ram, but the cost of the kvm, supplies from home depot, wires, etc drove the total investment up.

I spent the weekend preparing the helmer case. I cut the vents for the power supplies, made a door, and cut the plexiglass shelving. I still need to cut holes for the fans, but am waiting on the fans to come in the mail so I can best determine where / how they are placed.

Here is where it stands now. I'm pretty excited, and will post more as parts come in.

Just a word of caution.
I'd not over-clock the CPUs until you have everything running stable and cool at the standard clock speeds.

A good case is designed to make air flow around the components. With a home-made case you will almost definitely have to go through a few test/tweak cycles before you get the moving air to all the places it need to go.

I was going to get water cooling for the CPUs, but in hopes of saving some money I am going to see if I can get away with good ol' air cooling. Since heat in my tiny office is already an issue, that may as well be a factor.
